So this is licence bought from Adobe Store at 2007. Since then I've used the license for couple of months for exactly one project. I'm willing to sell it for BTC.
Instructions how the licence can change owner:

By looking at the Adobe Store prices in Finland upgrade to CS5.5 costs € 240.79 where as full version goes for € 845.79. I don't know about prices for other regions or if there is limitations to this in owner change but I'll do the research when I have possible buyer.
How much you think it's worth and how much would you pay? Basically last 3 years the licence has been useless for me so I can sell it cheap. Original price was € 699.
